handschmeichler 4.0

Hi,

i would like to share my latest prototype – the handschmeichler 4.0. Goal was to build an edc that will fit inside the small pocket on the right side of your jeans.

Some technical details about the hardware:

- 1 × 128 Gbyte USB Storage
- 1 x Atmel 32u4 µC
- 2 x Osram Oslon high Cri
- 1 x Osram Oslon Deep Red
- 1 x Nichia NCSU276A
- 1 x Bosch BME280
- 1 x TCS34725
- 1 x ADXL345
- 1 x selfmade 7135 driver
- 1 x Oled 128×32 Display
- 6 x tritium vial

it can messure:

- air temperatur
- air humidity
- air pressure
- altitude
- brighness in Lux (very accurate)
- light color in kelvin
- max lux memory
- angle (spririt bubble)

to turn on the light, there is a classical switch on the side. to change the brighness there is a poti beside the switch. to change the color from white to red or 365nm uv you have to long press the button when first page (flashlite page with battery status, brighness level status and led color information) is displayed.
to change to the next display site you have to short click. each page have some special function with long oder doubleclick.

the software takes more then 40 hours to complete. i´m not a complete noob in that, but also no specialist. the mechanical side takes more then 50 hours to complete. there was many work to fit all parts inside. the display circuit board alone tooks more the 3 hours, cause there was a lot to do to small down to fit inside.

Short Video demonstration:

Thanks for Looking, Markus

Looks fantastic, not cheap I’m sure, what sort of battery is in side and what capacity is it?

I’m guessing it’s lithium polymer. But I could be wrong hehe

That is quite different from the average flashlight, a great custom build! Smile Out of curiosity a few questions:

-what are the drive currents for the leds?
-are those small lenses before each led? and if they are plastic, does that interfere with the output of the Nichia (365nm version?)
-I’d love a look at the inside!!
-(my pet-subject Wink ) you state that the luxmeter is very accurate (accurate luxmeters are tricky to make), what sensor did you use, what is the Vlambda curve of the sensor and how does it deal with light that comes in from an angle (I see it has no diffusor)?

Hi,

- current for the white is 1050ma, red-700ma, uv-700ma.
- all glass lens
- i will make some pictures these days…
- yes, you are right. it is important that you messure with the right angle

datasheet:
https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&u...

the sensor can also messure rgb values, so there are some things more possible. first i´d like to include a rgb led, but i discarded that cause the space is really limited.
i did some messurements compared with my lx133 luxmeter, and the results where pretty good for this smal device. i don´t say this is accurate by <1%, but good for make some messurements when outside.

I just watched the video. Man, that is small! You fit a lot of cool features in such a tiny package. Beautiful work!

No one, after lighting a lamp, puts it away in a cellar nor under a basket, but on the lampstand, so that those who enter may see the light.

Hey Guys,

thanks for all the nice words. it was a pain to complete the Handschmeichler, cause all is very small. i will make some pictures from inside these days. all is wired with paint wire from an old transformer so it look really confused.

the body is made out of aluminium and stonewashed after grinding.

i have some new ideas to expand the software: shut off the display with a double click, cause this is really bright when use the red led at lowest level. and include a zero function to the spirit level to messure the absolute angle.

thanks again, Markus

This forum has a lot of members whose skills I only can admire, but never could copy.
Without putting them down, by comparing apples with pears and/or oranges, this is a work of art of a different category.

Just to have the vision to create such a complex device. And then fabricating it and making it function properly.
Absolutely magnificent!
In terms of skills: I’m from the other (far) side of the spectrum.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

Me too Henk… I’m learning equipment design now. Hope I could contribute to the community one day… Smile

Hi,

i build i new one for me with some additional cool features. I added a Ti Tmp007. This is a really small contactless ir temperature sensor.
At the top cover is a xml2-wrgb led. you can fade through the rainbow via the pot and regulate brightness of the selected color. You can switch to white light (mixed from rgb) and regulate brighness. You can randam fade through colors automaticaly and also regualte the brighness. Each die of this led is connected to a 7135, so 380mA. The alu board is glued to a small alu pedestal inside the case. so thermal transfer is given. the white led die is used for the activity state of the 128gb usb memory without a 7135.
The top cover is made out of a sandwich with 0,3mm carbon and 1,0mm red zeder wood. both is glued together with superglue and a lot of pressure. the wood is also stabalized with superglue under vacuum. all in all this was a long try and error to get a durable cover made out of wood.

It’s sort of like an old Ferrari- hand built, beautiful, and high performance in a tight package. Hard to imagine how to improve anything.
